Google + DomainSponsor Click Fraud via searchportal.information.com

The purpose of this page is to document click fraud on the Google AdWords search network.
These clicks originate from the Google AdSense for Domains program partner DomainSponsor
and are masked by searchportal.information.com URLs.
Tracking in web server log files, these referring URLs appear to involve search
queries but are actually clicks on links.
No actual search is involved - not even a direct navigation search.

Note the query= piece of the above searchportal.information.com URLs.
Normal search queries do not have the first letter of each keyword capitalized.
Searchers don't generally capitalize each individual keyword.
These queries are not search queries at all.
They are artificial searches, clicks on links on the iowagop.com domain,
masked by searchportal.information.com URLs in server logs. See this screenshot:

The reason this constitutes click fraud is not because these clicks originated from parked domains.
Generic domains that are parked can provide valuable clicks for advertisers.
This is click fraud because the clicks came from the Google AdWords search network,
not the content network, yet no actual search took place.
